Summary
San Antonio Elementary is a K–5 school in San Jose’s Alum Rock Union Elementary School District, serving 326 students in an area with several nearby elementary schools. In 2025–26, its results were below the district and state in ELA, math, and science; its ELA and math results were also second-lowest among five nearby K–5 schools with scores reported that year.
ELA and math are the school’s clearest challenges compared with nearby schools, the district, and California. ELA proficiency was 18%, compared with 31% in the district and 49% statewide; it was also 5 points below the nearby-school average, with only Anne Darling Elementary lower. Math proficiency was 16%, versus 22% in the district and 38% statewide, and 4 points below the nearby average; again, only Anne Darling was lower. Science is a relative strength among nearby schools: the school’s 20% proficiency was 5 points above their average and second-highest among the five schools, though still below the district’s 22% and the state’s 36%. Fourth grade stands out as a particular concern, with 10% proficiency in both ELA and math, the lowest results among the five local schools in those subjects.
Over time, ELA has been essentially flat and math has improved slightly from 2022–23 to 2025–26, while science has risen from 14% to 20%; in the latest year, ELA and math fell by 4 and 6 points, respectively, while science rose by 7 points. Chronic absenteeism also deserves attention: it reached 23% in 2025–26, above the state’s 18% and the district’s 17%, and 18 points above the school’s 2021–22 rate. SchoolDigger places the school at the 7th percentile with 0 stars, down 33 percentile points from 2018–19; enrollment and its 23.2 student-teacher ratio are close to nearby-school averages. In 2024–25, 92% of students were free/reduced lunch eligible, the highest share among nearby schools with the same measure and year. One older bright spot: SchoolDigger ranked how well the school served English Language Learner students at the 44th percentile in 2023–24, compared with the school’s overall 14th percentile that year; subgroup data provided end in 2023–24.
